Very nice piece mahjix, few minor points of criticism though:

Some anatomy issues such as her neck and torso which look kind of weird and her legs look really small in comparison to the rest of her body. Another issue is the foreshortening and placement in space on her legs, because she seems to be sitting quite in the center of the glowing cubething while the pose of her legs and feet suggests she's sitting on the edge of it.

Minor inconsistency in highlights if you compare the feet to the black goo for example. The feet show nearly no outline while the black goo shows a thick outline even though they're getting lit by the same lightsources.

Some pretty inconsistent lighting from below. She's being lit from directly underneath her while she's still catching strong light on the bottom of her face and near her shoulder even though there's a feather edge blocking light and the projected shadow of the feather edge suggests lighting from a close source that's up high, because if the light came from underneath, the shadows would be much longer and covering up most of the face. Some more minor lighting inconsistencies like that in other spots like on her ribcage.

Other than that very nice rendering job.
